SPECIFICATION forming part of Letters Patent No. 538,639, dated April30, 1895.

Application filed February 26,1895. Serial No. 539,752. (No model.)

To all whom it may concern:

Be it known that we, FREDERICK JUSTIN BOURN and WILLIAM REUBEN HALE, ofGualala, in the county of Mendocino and State of California, haveinvented a new and Improved Wrench, of which the following is a full,clear, and exact description.

Our invention relates to an improvement in wrenches, and especially toan improvement in that class of wrenches applicable to vehicle wheels,and it has for its object to provide a wrench which will simultaneouslyclamp the hub of the wheel and thelock nut of the axle, whereby when thewheel is removed from the axle the lock nut and its washer will he heldin their proper relation to the hub and be prevented from fallingto theground or being lost, and whereby also when the wheel is again returnedto the axle spindle the nut will immediately engage with the thread ofsaid spindle, thus preventing the soiling of the hands in removing thevehicle wheels, and permitting the oiling or lubricating of axles to beconveniently and expeditiousl y accomplished.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in both views.

Figure 1 is a perspective view of the improved wrench and a portion ofthe hub of the vehicle-wheel to which it is applied; and Fig. 2 is avertical section through the movable members of the wrench, the shankbeing in side elevation, with the exception of the jaw attached thereto.

In carrying out the invention the shank of the wrench is preferably maderectangular in cross section, and at its handle end is provided with areduced cylindrical and exteriorly threaded section 11, while at itsopposite end ajaw 12 is rigidly secured, the said jaw being made toextend beyond both sides of the shank, but a greater distan oe on oneside than the other, and that portion of the jaw which extends thegreater distance beyond the shank is provided with a concaved 1ongitudinal recess 13 in its inner face. Adjacent to the said jaw 12 a nutclamping jaw 14 is held to slide upon the said shank, and this nutclamping jaw likewise extends beyond both sides of the shank, and whatmay be termed its inner end is connected with the fixed jaw 12 of theshank through the medium of an adjusting screw 15, the screw being heldto turn loosely in the nut-clamping jaw 14,

and it is passed through an aperture in the fixed jaw 12, the wall ofwhich is threaded correspondingly to the screw. Thus it will be.observed that at the outer side of the wrench the extended portions ofthe jaws 12 and 14 may be used as an ordinary monkey wrench.

A handle 16 is made to fit over the threaded end of the shank 10, thesaid handle having a longitudinal threaded bore made therein,corresponding to the thread of the shank; and a hub-clamping jaw 17 isheld to slide upon the handle end of the shank, being providedpreferably with an integral sleeve 18, which has substantially aswivelor loose connection with the handle 16,whereby when the handle isscrewed inward or outward upon the threaded end of the shank, the jaw 17will be correspondingly moved, and in the inner face of this jaw 17 aconcaved longitudinal recess 18 is formed, corresponding to the recess13 in the fixed jaw 12. A mating jaw 19 to the nutclamping jaw 14 islikewise held to slide upon the said shank, the jaws 19 and 14 being ofless length than the jaws 12 and 17, and the jaw 19 is connected withthe jaw 17 operated from the handle, by means of an adjusting bolt 20,which is loosely mounted in the jaw 19 and has screw connection with thejaw 17. Thus when the handle 16 is manipulated, the hub-clamping jaw 17and the nut-clamping jaw 19 will move in unison.

In the operation of this wrench, the nut clamping jaw 14 is adjusted bymeans of the screw with relation to the fixed jaw 12, so that the innerjaw 14 will engage with the nut of an axle when the jaw 12 is brought inengagement with the outer face of the collar 21 of a hub of a vehicle;and the same adjustment is made through the medium of the adj ustingscrew between the adjustable jaw 17 and the inner connected jaw 19.

In applying the wrench, the aforesaid adjustment having been made, thehandle is screwed upward or outward until the handle jaws 17 and 19 arein such position that they will not engage with the collar of the hub orthe lock nut 22, when the fixed jaw 12 and the nut-clamping jaw 14 arein such position. This having been accomplished and the jaws 12 and 14being in engagement with the nut and hub collar, the handle 16 isscrewed downward until the jaw 17 shall have clamped the collar of thehub, and the inner jaw 19 shall have engaged with the nut. Thus the nutwill be firmly clamped between the intermediate jaws 14 and 19, whilethe collar of the hub will be firmly held between the outermost jaws 17and 12. The recesses in these jaws conforming to the contour of the saidcollar enable them to hold the collar the more firmly. Therefore, whenthe wheel is removed from the axle spindle, the lock nut will be held inthe position with relation to the hub that it previously occupied, andconsequently will not be lost or dropped to the ground, and willfacilitate the replacement of the wheel when required.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- I 1. A wrench, the same consisting of a shank,a jaw at the outer end of the shank secured thereto, an adjustablehandle carried by the shank, a jaw connected with said handle, andintermediate jaws having an adjustable connection one with the handlejaw and the other with the opposing outer jaw, as and for the purposeset forth.

2. A wrench, the same consisting of a shank, a jaw fixed to one endthereof and extending beyond opposite sides of the shank, a handleadjustable upon the shank, a jaw connected with said handle and carriedthereby, and two intermediate jaws, one opposite the fixed jaw andextending beyond both sides of the shank, and the other being oppositethe handle jaw, both intermediate jaws being adjustably connected withthe outer jaws adjacent to which they are located, substantially as andfor the purpose set forth.

3. In a wrench, the combination, with a shank, having a threaded handleend, and a fixed jaw at its opposite end, a handle adapted to be screwedupon the threaded portion of the shank, a jaw having a loose connectionwith the said handle and carried thereby, and two intermediate jaws heldto slide upon the shank, of less length than the outer jaws, each of theintermediate jaws having an adjustable connection with the outer jawadjacent to which it is located, substantially as set forth.

4. In a wrench, the combination, with a shank having a threaded handleend, a jaw fixed at its opposite end, extending beyond both sidesthereof and provided with a recess in the inner surface of its innerend, and a handle screwed upon the threaded portion of the shank andadapted to have movement parallel with the shank, of a jaw recessed uponits inner face and having a loose con nection with the said handle,intermediate jaws, one opposite the handle jaw and the other oppositethe fixed jaw, the said intermediate j'aws being shorter than the outerones, and the jaw opposite the fixed jaw extending beyond both sides ofthe shank, and adjusting screws loosely connected with the intermediatejaws and having threaded connection with the outer jaws adjacent towhich the fixed jaws are located, substantially as and for the purposeset forth.
